Detailed Description
The present invention will be further described with reference to the accompanying drawings and specific embodiments so that those skilled in the art can better understand the present invention and can implement the present invention, but the embodiments are not to be construed as limiting the present invention.
As shown in fig. 1-4, a non-contact ultrasonic liquid level monitor comprises a host and a plurality of ultrasonic sensors, wherein the ultrasonic sensors are in signal connection with the host. Specifically, the host computer includes casing and singlechip, and the singlechip setting is connected with the singlechip at the inside of casing, a plurality of ultrasonic sensor. A plurality of ultrasonic sensor set up on the not co-altitude position of the outer wall of water tank, according to the current strength that the ultrasonic sensor of co-altitude formed, judge the height of inside precipitate of water tank and water level.
This non-contact ultrasonic wave liquid level monitor's application mode, when the sensor by the water tank outer wall to inside when taking place the ultrasonic wave, the ultrasonic wave transmits and produces to show the transmission and form the echo after touching the medium in water tank and medium to receive vibration formation electric current on the piezoelectric wafer of sensor, because the difference of ultrasonic wave contact medium kind, the medium of general detection mainly has: air, water, mud and suspended matters form different current intensities, and specific components in the water tanks at different positions can be judged after processing current signals with different intensities according to a logic algorithm edited on a single chip microcomputer in advance;
the method for judging the media comprises the steps that specific numerical values are related to the cross-sectional area of a water tank and the performance of an ultrasonic sensor, the current intensity formed by each medium can be obtained through testing, the range of the current intensity of each medium is set, data are recorded, certain upper and lower error values of the current intensity numerical values of different media are given, the feedback numerical value of air is obviously higher than other numerical values, the numerical value of water is centered, the value of suspended matters and mud is the lowest, the error value can be set within about 50% of the upper and lower range, and whether the media at different heights in the water tank are water, air, mud or suspended matters or not is judged through comparison of different numerical values during application.
In general, the number of the ultrasonic sensors is four, and the four ultrasonic sensors are arranged on the outer wall of the water tank and form a water shortage level, a water supplement level, a full water level and a water passing level from bottom to top. And the water tank is linked with a system of the water tank, when the water level is lower than the water shortage level, the water inlet of the water tank automatically feeds water, and when the water level is higher than the full water level, the water inlet stops feeding water. When the sediment is lower than the water shortage level, the sewage discharge port is closed; when the sediment is higher than the water shortage level, the sewage draining port is opened. When the water level is higher than the over-water level (warning water level) due to the influence of the sediment, the equipment starts to alarm to remind workers to clean mud.
In addition, this non-contact ultrasonic wave liquid level detection appearance still includes switch and RS485 interface, makes things convenient for artificial control and receives and output signal through RS485 crossover sub, makes things convenient for the device to merge with the access of integral control integration network, provides the possibility for the unified management of production. Device internal electronics such as: the single chip microcomputer and the like adopt a PCB (printed Circuit Board) nanometer waterproof coating technology, so that internal elements have good heat dissipation performance on the basis of certain waterproofness, and meanwhile, a vacuum rubber plate is adopted in a stainless steel machine body for heat insulation treatment, so that the whole equipment has good adaptability and stable working capacity in a high-temperature and humid environment.
The front side of the host is also provided with a control panel which is connected with the singlechip and used for displaying the condition of the water tank sensed by the ultrasonic sensors, for example, when the water level is lower than a water supplementing level, a water supplementing level indicator lamp for indicating the water level is lightened; when the water level is higher than the full water level, a water shortage level indicator lamp for indicating the water level is turned on; when the sediment is higher than the water shortage level, a water shortage level indicator lamp for sediment position indication is turned on, and the like.
The above embodiments of the present invention are not right the utility model discloses the limited protection scope, the utility model discloses an embodiment is not limited to this, all kinds of basis according to the above-mentioned of the utility model discloses an under the above-mentioned basic technical thought prerequisite of the utility model, right according to ordinary technical knowledge and the conventional means in this field the modification, replacement or the change of other multiple forms that above-mentioned structure made all should fall within the protection scope of the utility model.
